JOINING MEANS FOB ANGLES, CHANNELS, AND THE LIKE.

Application led July 2, 1915. SerialNo. 37,656.

To all lwhom z't may concern Be it lmown that I, FRANK E. GETTS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, useful Improvement in Joining Means for Angles,I Channels, and the like. This invention relates to joining-means for angles, channels and the like.

Heretofore in the art'very considerable difficulty has been experienced in joining structural-shaped bars. This has been particularly troublesome ,in field assembly of parts of transmission towers, windmill towers and similar structures which are shipped in parts or sections and lmust be assembled inthe field witlias few and as simple tools and equipment as possible.`

The practice` of bolting angles, channels' and similar structural lparts together has been found unsatisfactory because of the It is impossi- 4. ble to drawl the parts closely enough tocal.

improved joining-means gether to obtain proper surface friction without using so manybolts as to make the cost prohibitive and the structure impracti- The time required for fastening bolts is in excess of the time'required toafasten number of rivets, and the cost is generally more. However, riveting together of parts in the field is often impractical and is at times undesirable, because it may be found necessary to separate the parts.

The object of my invention is to provide for-angles, chanwhich I' shall 'term strucnels and the like,

allow ofjoining the said a of effort and time.

A further object is to provide a joint which may be easily assembled or disassembled and which will employ a minimum of material to maxmuinadvantage.

' bolts under tension have invented a certain new iand A lies inside of the corner of and depend the projections instead of the shearing strength of the bolts, to hold the parts together.'

I shall'now describe, with the aid of the accompanying drawings, which illustrate a preferred embodiment of myinvention, a particular manner in which the invention may be practised.

Figure 1 illustrates a joint made between a plate and an angle, employing my invention. Fig. 2 illustrates a plan view of the saddle-clips, the end of the angle and the extending end of .l the gusset. Fig. 3 is a cross-section taken on the line 3-3 of Fig. 2. Fig. 4 is a bottom plan view showing the inside of the gusset andthe heads of the fastening bolts seated in their sockets. Fig.

form a joint. Fig. 7 is a perspective view of thecoperating gusset-plates. Fig. 8 is a perspective view of the saddle-clips. Fig. 9 is -a cross-sectional view Iillustrating the manner in which the invention maybe ap plied in joining a gusset and a channel-bar; and Fig. 10 is a perspective view of the end of a channel-bar punched and 'stamped to form a joint such as shown in Fig. 9.

In Fig. 6 I have shown the id of an angle-bar 1 havingoifsets 2 stamped in the side or liange of the bar to form the depressions on the outside and projections on the inside, as may be seen more clearly in Fig. 3. Suitable holes 3 are punched,

drilled or otherwise formed in the corner f of the angle-bar in line with a pair of projections 2. The gusset 4 shown in Fig. 7 the angle-bar 1 and is formed with notches or depressions 5 which register with the olfsets 2 in the angle-bar 1. vided in the center of the gusset, these holes registering with the holes in the angleb'ar. The gusset' 4 may be :formed of malleable castings-of'plain cast iron, forgings, or the like, and maybe made in any shape desirable to join the structural angle-bar to any other part.

Angle-clips 7 (see Fig. 8) are seated or Suitable bolt-holes 6 are pro! saddled upon the corner of the angle-bar sides of the clips by means of the strengthening webs or flanges 12. The inside sur'- face of the saddle-clips is provided with beads 13 which seat in the depressions 2 and serve to hold the depressions in the notches 5 in the gusset-plate.

The gusset-plate 4 is provided with bosses 14 of a size suitable to receive ythe head 15 of the clamping-bolt 11 and at the same time prevent the head of the bolt from turning.

Fig. 3 shows, in across-sectional view, disposition of the parts when the clampingbolt 11 is drawn up. Although the bolt 11 passes diagonally through the surfaces to be clamped, it is not placed under uneven strain, dueto the seats provided for it. rIhe diagonal stressesupon the clamping surfaces are a distinct advantage and tend to keep the parts tight at all times.

The gusset-plate 4 maybe made in any convenient shape for joining an angle-bar to any desired part.' yWhere a number of angle-bars 'are to be secured together, a suitable casting or stamping maybe employed and very little trouble in assembling or disassembling the parts is experienced. The structural bar is not weakened to any appreciable extent by the depressions 2, as these parts are merely offsets and are not any appreciable diminution/in the thickness of the material. It is to be noted that the interior surface of the gusset-plate and of rIhe same size angle or saddle-clips v7 which serve to Ijoin one Isize of V-shaped angle-bar, may be employed to join a cori/'esponding sized channel-bar to the respective gusset-plates. It is obvious that different size parts will be employed with different standard sizes of bars.

I do not desire to be confined to the precise details of construction shown and described, but intend that my invention shall extend to such variations and modifications as may suggest themselves to one skilled in l the art.

the angle-clips is preferably relieved to prevent binding at the corner and to secure a good gripping action.

In Figs. 9 and 10 I have illustrated the manner in which my invention may be applied to joining channel-bars or beams to other'parts. In this case the channel-beam 16 is provided with the holes 3 running diagonally through the corner and with the of. Saddle-clips 7 depressions 17 in the sides of the channel, and a large depression 18 in the web thereare employed upon the i 'outside of the channel-beam and the beads v13 thereof seat in the depressions 17 and 18.

`The gusset 19 is formed to coperate with the channel 16 and has depressions registerlng with the depressions 17 and 18'and is provided with suitable bolt-holes running diagonally through .the'cornerto allow the bolt 11 to pass therethrough. rIhese bolts grip the channel between the gusset and the saddle-clips in a manner similar to the funct1on they perform in joining the ll-shaped angle-bar to its coperating gusset.

Wha-t I claim as new and desire to protect by Letters Patent of the United States is the following:

-1. In combination, a structural angle-bar, a gusset, said angle-bar having offset depressions in the flanges thereof, coperating seats on said gusset, a saddle-clip seated on said angle and serving topress said offset parts together, and a bolt passing through the center of said saddle-clip and through said angle-bar and gusset.

2. In combination, a V-shaped angle-bar, a coperating gusset conforming to the interior surface of said angle-bar, a saddle-clip seated on the outer surface of said anglebar, said parts having registering offsets to prevent endwise motion of the parts, and a bolt passing diagonally through the corner for clamping said parts together.

3. In combination, a V-shaped angle-bar, a gusset conforming to the interior surface thereof, a saddle-clip conforming to the outer surface of said angle-bar, said parts having laterally-offset portions to prevent endwise motion, and having a bolt-hole through the corner Aof said parts, a boss on said gusset and aboss on said saddle-clip, and a bolt passing through said parts and coperating with said bosses.

4. In combination, a structural' bar having an -angle therein, lateral offset portions disposed on each side of said angle, a gusset fitting on the inside surface of said bar, a saddle-clip fitting on the outside surface of said bar, said j" parts having lateral `offset portions coperating with the offset p ortionsof said bar, and a bolt for clamping said parts together.y i

`5. In combination a structural wrought metal angle bar having a convex side and a concave side, agusset nesting into said concave side and a bolt passing centrally through said gusset and said angle bar for xclamping the gusset and the bar together yios metal bar having an angle therein, laterally centrally through said gusset and said bar offset portions disposed on each side of the for wedging said gusset and bar together angle, an angular gusset adapted to nest in nested relation. Y l With said bar, said gusset having laterally In Witness whereof, I hereunto subscribe 10 5 offset portions adapted to nest with the ofmy name this 29th day of June A. D. 1915. set portions of said bar and bolts passing FRANK E. GETTS.
